Specification of Letters Patent.

Patented Dec. 3; 1907.

Application filed November 15 1906. Serial No. 343,648.

To all whom it may concern:

Be it known that I,-ROLAND H. ELKINS, a citizen of the ,-United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new and useful Improvements in Distributers for Force- Feed Lubrieators, of which the following is a specification. v

My invention relates to the distribution of oil in the lubrication'of machinery when ap-' plied by force feed lubricators.

.The invention is designed as-an'improvement uponmy distributor for force feed lubri'cators for which Letters Patent were issued on November 20th-1906, Number 836,308.

, The object as in the former invention is the distribution automatically of oil in fixed ratios and against difi'erent pressures withoutthe use of separate lubricators or pum s.

It is especially adapted for automo iles and locomotives, and, in fact, to all kinds of machinery having many separate parts for lubrication; The lubricant is furnished to the different parts through pipes leadingfrom the distributor and the quantit of lubricant for all the parts is determined from the lubricator or pump. The ratio for each part is determined by the area ofthe opening from' which the oil is discharged from the distributer.

Reference is now had to the accompanying a perspective view of lever showing the slot:

therein. a

Referring to the illustration, A is the frame supporting a round, horizontal. shell B, in which operates a central plug 0 having at its ends the stems c and d.

To the outer endof the shell is screwed a yoke I) through which the end of the stem, a, freely passes. Near the shoulder of the lug the stem is threaded and is encircled y a knurled nut e. Between the nut and the outer end of the yoke iii-spring E encircles the stem and sustains the-pressure of oil from the lubricator. The tension of the spring may be regulated b adjusting the nut e. Packing'glands F an F and packing with the lubricator, t

by that fed .f, f around the outer ends of the plug prevent leakage of oil from the shell-. The oil] enters the shell through the pipe 9, which is connected with the lubricator or pump, and the pipe it, both being located in the frame A. Either end of the pi e 9 may be connected he end not in use being stopped by a plug it. formed integralwith the frame, are a series of vertical shells G, g communiclitinig with tile i e ,throu ht e i esg,gf ea ingtot e i nlleri br of ifhe sh ll s As many vertical shells may be provided as there are separate parts of the machine to be lubricated, the pipes j, j, conveying the oil to the various parts. In each vertical shell is a taper plug H which-is threaded near the lower end and screwed into the interior of the shell which is also threaded to receive the lug as shown in Fig. 2. The plug is smaller elow the thread and tapers at the end, and the interior of the Above the pipe g and f shell is slightly larger and of corres onding shape. Packing glands I, I, and pea ing 01, i, surround the plugs in the upper ends of the shells and prevent leakage. 1

ToAthe. outer end of the stem of the plug C is secured a bar J having a central slot which incloses the stems or up er ends ofthe vertical plu s H,'H. The ar is provided. with arms, K, formed at right angles to the barand integral with it, each arm also having acentral slot normally situated directly opposite the plug stems. Directly underneath said arms are arms L having corre-- spondinglycentral slots, and in one end an annular opening in which are fitted the stems or upper ends of the plugs H. The arms L are secured to the stems by means of the screws Z. At the ends inclosing the plugs the arms have lugs or shoulders m, to provide a space between them and the arms K. Eachrset or pair of arms is connected by bolts M having central heads n, and nuts 0 at the upper ends. These bolts may be adjusted at any place in the slots by means of the nuts. The arms K and L thus form levers for turning the vertical plugs in the screws in the interior of the respective shells,

thus raising the point of the plugs out of their seats in the pipes g and permitting the 'oil to enter the interior of the shell.

As the oilis' forced from the lubricator or ump through the pipes g and it into the shell 5, it crowds the lug C toward the spring, pulling the stem and bar J in the same d1- rection. Themovement communicated by lubricant the arms'K and L to the plugs'l l, turns the plugs in the screws and raises them from their seats; The distance each plug is raised depends ,upon the position of the bolt connecting the arms. Thus, if the bolt is adjusted at the outer end of the-slot the lever islonger and the plug is not turned so far in the screw as if adjusted at theinner end, and consequently the plug is only slightly raised.

When the bolt is atthe inner end of the slot.

the plug is turned farther and raised'to the full capacity .of-the lever. The quantity of oil required to pass through an .outlet'pipe. to the machinery may be regul the vertical shells passes out through the pipes to the machinery to be lubricated.

many shells'as required may be pro-.

vided. The ratio" of discharge through the differentv pipes 1 is automatically maintained by the tension of the sfprin'g at the operating ,p ug-. The; tension 0 the spring -must always be' strong enough to overcome the greatest pressure from any part of the machinery, and must be overcome by the force of the lubricator or pump before any oil willpass out of the distributer.

Having described my invention what I ing communication with the supply main of a 'lubricator, an operating plug 'therein against which the lubricant presses, a spring to sustain the pressure of the lubricant, shells leading from the lubricator into which the lubricant passes, plugs seated in the said shells to arrest the flow of the lubricant, le-.
